UC1 - External Aircraft Aerodynamics

UC1 simulates steady airflow at subsonic speed and computes typical characteristics like air velocity and direction, pressure and turbulence via the CODA CFD software and the FlowSimulator framework.

Do you want to request support from EXCELLERAT staff or consulting on this Use Cases?

UC1 is dedicated to the high-fidelity numerical simulation of turbulent flows around complex aircraft configurations at high Reynolds-Numbers on unstructured grids. It solves the Raynolds-averaged Navier-Stokes equations (RANS) with a Spalart-Allmaras turbulence model (SA-neg). It uses finite-volume discretization on unstructured grids to allow for high accuracy, especially, in the boundary layer. The use case is designed to evaluate performance and scalability on current and upcoming HPC systems by using a hybrid MPI/GASPI and OpenMP parallelization and the inclusion of hardware accelerators like GPUs.
